Set-up Procedures of IVMS Start Mode
1 Set the protection for the PM motor.
• Setting the over current detection level [bb160]
• Setting the electronic thermal level [bc110]
Precautions for Correct Use
• The over-current detection level should be set appropriately by taking into account the maxi-
mum current (demagnetization level) of the PM motor to be used. Set the over-current detec-
tion level so that the SM (PMM)’s maximum current (demagnetization level) is not below
150% of the over-current detection level.
•See also 6-6-1 Electronic Thermal Setting on page 6-48 and set it appropriately.
2 Set the PM motor’s Plate Data.
• Setting the capacitance [Hd102]
• Setting the number of poles [Hd103]
• Setting the base frequency [Hd104]
• Setting the maximum frequency [Hd105]
• Setting the rated voltage [Hd106]
• Setting the rated current [Hd108]
Precautions for Correct Use
See also 6-2-1 Motor Basic Settings on page 6-8 and set them appropriately.
3 Set the PM motor constants.
• Setting the motor constant R [Hd110].
• Setting the motor constant Ld [Hd112].
• Setting the motor constant Lq [Hd114].
• Setting the motor constant Ke [Hd116].
• Setting the motor constant J [Hd118].
Precautions for Correct Use
See also 6-2-2 Motor Constant Setting on page 6-12 and set them appropriately.
4 Conduct the IVMS auto-tuning
• Set the control mode [AA121] at 12 (SM-IVMS).
• Set the auto-tuning selection [HA-01] at 03 (IVMS).
• Input the command for starting the auto-tuning (operation command).
• The inverter is in an automatic operation.
• Tuning is finished.
